Answer
Substance A which is harder than pure metal and used in cutting tools can be an identified mixture of Iron and Chromium.
Explanation
## Step 1: Understanding the questionThe question asks about the identification of a material which can be a mixture of two certain metals (anonymized as many metals for clarity), according to the table given. ## Step 2: Gathering clues from the tableObserving the table and assessing given options (substances A,B,C), it can be inferred rather mechanically. Since every choice known to mix would exhibit a unique property which relates to their application.## Step 3: Identifying mixturesKnown from prior knowledge, iron and chromium in combination result in an alloy which is much harder than single pure metals. This elevated degree of hardness finds its application in manufacturing tools which need to withstand pressure and cutting force.
